Brake for a fishing reel

ABSTRACT

A magnetic brake fishing reel is provided which includes a reel body rotatably supporting a spool and a drive mechanism supported to the reel body and having a clutch for releasably driving the spool. The magnetic brake has an electric conductor which is rotatable together with the spool. A magnet holder having at least one magnet is disposed opposite to the conductor. An adjustor which moves the magnet has an operating member positioned such that it is hand-operable by an angler gripping a fishing reel rod on which the reel is mounted.

FIELD OF THE INVENTION

This invention relates to a fishing reel, and more particularly to afishing reel having a spool and a magnetic brake for reducing an overrunof the spool.

BACKGROUND OF THE INVENTION

Conventionally, a fishing reel is well-known which has a spool supportedrotatably to a reel body, a drive mechanism for driving the spool, and aclutch mechanism interposed in a driving force transmission system ofthe drive mechanism, the clutch mechanism engaging to rotate the spoolthrough the drive mechanism for winding a fishing line on the spool anddisengaging to allow the spool to freely rotate for casting a fishingline.

The line wound onto the spool, when cast, is drawn by the weight of afishing rig at the end of the line, at which time the spool rotatesfaster than the drawn line to cause a backlash, whereby the line may gettwisted or enter between the spool and the reel body. Therefore, a brakemeans is provided to control the free rotation of the spool.

The brake means generally employs a centrifugal brake which exerts thebraking action by slidably contact of brake shoes with a brake drum.Accordingly, a problem exists in that the braking effect varies due towearing of the brake shoe.

In order to solve the above problem, a fishing reel provided with amagnet brake has been proposed which has a magnet and an electricconductor. One of the magnet and electric conductor is fixed to the reelbody and the other rotates together with the spool to generate an eddycurrent by the rotary flux, so that the rotary member at the brake,under Fleming's left-hand rule, is subjected to a magnetic force in adirection reverse to its rotation, thereby exerting braking effect onthe spool. The stationary member is made movable with respect to thereel body and an adjuster is provided axially outwardly of the spool andis operable to adjust the relative position of the magnet with respectto the electric conductor.

This braking method, which has no contact portion, can solve the problemof changing the braking effect due to the wearing of a braking memberand also the adjuster can control the braking action in proportion tothe number of rotations of the spool. However, the adjuster cannotadjust the braking effect in response to variations in the number ofrotations of the spool. In other words, if a large braking effect ispreadjusted to avoid the occurrence of backlash, the spool, at theinitial stage of casting, is subjected to a large braking effect whichresults in a smaller casting distance. On the other hand, the brakingeffect, when preset to a minimum with respect to the number of rotationsof the spool at the initial stage of casting, will permit casting to agreater distance, but easily creates backlash of the spool.

SUMMARY OF THE INVENTION

In the light of the above problem, this invention has been designed. Anobject of the invention is to provide a fishing reel which can cast afishing rig to a greater distance while having a braking effect on thespool which is desirably adjustable by an angler and which is easilyoperable to prevent the backlash of the spool during casting.

The present invention has the basic idea that the braking effect on thespool is adjusted corresponding to variations in the number of rotationsof the spool. A fishing reel of the invention, which is provided with amagnet brake comprising a magnet and an electric conductor fordiminishing an overrun of the spool journalled to the reel body, ischaracterized in that an adjuster is operated to adjust the brakingaction by the magnet and is provided with an operating member operableby the finger of angler's hand gripping a fishing rod carrying the reelbody to control the braking effect on the spool during the casting.

The fishing reel of the invention provided with the adjuster andoperating member as abovementioned, allows the angler to merely touchhis finger to the operating member to thereby increase the brakingeffect corresponding to the number of rotations of the spool.Accordingly, while the adjuster can adjust the braking effect to aminimum, the occurrence of backlash is reliably prevented. Also, theminimum braking effect can be preset to minimize rotational resistanceagainst the spool at the beginning of casting, resulting in casting ofthe fishing line to a greater distance.

This invention alternatively may provide two first and second adjusters,the first adjuster adjusting the braking effect on the spool to aminimum and the second one providing an operating member operable by thefinger of angler's hand gripping the fishing rod carrying the reel body,so that the operating member allows the second adjuster to change thebraking action having been adjusted by the first adjuster.

Thus, while the braking action at the beginning of casting isadjustable, the angler can merely touch his finger to the operatingmember, thereby increasing the braking effect corresponding to anincrement in the number of rotations of the spool.

Hence, backlash can reliably be prevented even with the braking effectadjusted to a minimum at the beginning of casting. The first adjusteralso can preset the braking effect to a minimum, thereby minimizing therotational resistance against the spool at the beginnging of casting andpermitting casting to a greater distance.

These and other objects of the invention will become more apparent inthe detailed description and examples which follow.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawing, a reel body A comprises a pair of first andsecond side frames 1 and 2 opposite to each other at a given interval,the first side frame 1 comprising a side plate 12 having at the center abearing housing 11, a doubling plate 13 attached to the outside of sideplate 12, and a cup-like cover 14 attached to the outside of doublingplate 13, the second side frame 12 comprising a side plate 22 having atthe center a bearing housing 21 and a cup-like cover 23 attached to theoutside of side plate 22, and the bearing housing 21 housing therein amagnet brake 5 to be discussed below.

A spool shaft 4 having a spool 3 is journalled to the first and secondside frames 1 and 2 through bearings 10, and extends at one endoutwardly to project through the first side frame 1, so that theextension therein carries a pinion 6 rotatably and axially movably.Between the pinion 6 and the spool shaft 4 is provided a clutch means 7engaging or disengaging through a clutch lever 81 at a clutch operatingmechanism 8.

A handle shaft 30 is supported rotatably between the doubling plate 13and the cover 14 through a support shaft 9, projects at one endoutwardly from the cover 14 to fix a handle 31, and supports at theother end a master gear 32, a friction plate 33, and a return plate 34having a plurality of clutch pins 34a, thus constituting a drivemechanism.

The friction plate 33 and return plate 34 are fitted onto the handleshaft 30 in relation of being rotatable not relative thereto buttogether therewith, the master gear 32 being fitted freely onto thehandle shaft 30 to thereby transmit the rotation therefrom to the mastergear 32 through the friction plate 33.

In addition, the press-contact strength of friction plate 33 to themaster gear 32 is adjustable by use of an adjuster 35 screwable with oneend of handle shaft 30.

The clutch means 7 comprises flat faces provided at an intermediateportion of spool shaft 4 and a cylindrical portion provided at thepinion 6 and having a not-circular inner surface engageable with theflat faces, the cylindrical portion disengaging therefrom by operatingthe clutch operating mechanism 8, thereby allowing the spool shaft 4 andthe spool 3 thereon to freely rotate.

The clutch operating mechanism 8 comprises a clutch yoke 82 carrying thepinion 6 and urging it always in the direction of engaging the clutchmeans 7, the furcate clutch lever 81 having an urging portion 81a tourge the clutch yoke 82, and the return plate 34, the clutch lever 81being mounted to the doubling plate 13 in relation of being movable inreciprocation perpendicular to the spool shaft 4 through a pin 83 and anelongate slot 84, and always biased in the direction of backwardmovement by a return spring (not shown). The clutch lever 81 is pushedto move the clutch yoke 82 axially of spool shaft 4, thereby moving thepinion 6 in the direction of disengaging the clutch means 7 and thehandle 31 is rotated to hit the clutch pins 34a against a contact member(not shown) provided at the utmost end of clutch lever 81 to restore theclutch lever 81 by a spring force of a return spring, thereby moving thepinion 6 by the urging force of clutch yoke 82 in the direction ofengaging the clutch means 7. In addition, the clutch lever 81 isswingable around the pin 83 at the doubling plate 13 and has at theutmost end an engaging portion, so that the engaging portion engageswith a cutout stepped portion at the plate 13 to hold the clutch lever81 in the position where its forward movement terminates.

Referring to FIGS. 1 and 2, the fishing reel constructed as foregoing isprovided in the bearing housing 21 with the magnet brake 5 comprising amagnet 50 and an electric conductor 51. The electric conductor 51 iscylindrical and mounted concentrically to the spool shaft 4 or spool 3.A magnet holder 52 of non-magnetic material has at the center anelliptic shaft bore 52b and at the outer periphery a magnet support 52afor supporting the magnet 50 opposite to the inner periphery of electricconductor 51, and is supported at the shaft bore 52b radially movablyonto the outer surface of a support cylinder 21a provided at the centerof bearing housing 21. A guide bore 21c for guiding the magnet holder 52radially is provided at the bottom wall 21b of bearing housing 21 andapart from the center thereof, into which an engaging projection 52c,provided at the side of holder 52, is inserted. A disc-like adjuster 53having a knob 53a for rotary operation is supported rotatably to asupport portion 21d at the outer surface of bottom wall 21b of bearinghousing 21 and is provided at the inner surface with a cam groove 53bformed in a circular arc shifting circumferentially from the outerperiphery toward the center of adjuster 53, the cam groove 53b engagingwith the engaging projection 52c at the holder 52. The knob 53a isexposed outwardly from the cover 23 to be operable from the exterior, sothat the adjuster 53 is rotated through the knob 53a to change theengaging position of engaging projection 52c with the cam groove 53b tomove the holder 52 radially with respect to the support cylinder 21a,thereby adjusting the magnet 50 at the holder 52 in position withrespect to the electric conductor 51. At the exposed portion of adjuster53 outward from the reel body A is provided an operating member 54 whichextends along the surface of cover 23 and projects radially of the spool3 so that the angler can operate the operating member by his handgripping the fishing rod (not shown) to increase the braking effect onthe spool during the casting.

The magnet is supported at one side of the outer periphery of holder 52and positionally adjustable from the position where the clearancebetween the magnet 50 and the electric conductor 51 is the maximum (theposition shown in FIG. 3) to the position where the same is the minimum(the position shown in FIG. 4). Also, the magnet 50, as shown, comprisesa N-pole magnet and two S-pole magnets at both sides thereof and isfixed to the support 52a at the outer surface of holder 52 through afixing means, such as an adhesive. Alternatively, the holder 52 may bemade from synthetic resin and the magnet 50 may be embedded in theholder 52 when molded.

The guide bore 21c provided at the bearing housing 21 is made ellipticso as to prevent the holder 52 from rotating with respect to the supportcyllinder 21a and allow the holder 52 to move radially only with respectthereto.

The operating member 54 comprises a boss 54a and an operating portion54b extending radially therefrom and preferably is mountedangular-adjustably to the adjuster 53 through the boss 54a. The adjuster53, as shown in FIGS. 1 and 2, is provided at the exposed portion with aprojection 53c having at the outer periphery a number of serrations andthe operating member 54 has at the boss 54a a bore 54c having a numberof serrations engageable with those at the projection 53c, the bore 54cbeing fitted onto the projection 53c through engagement of serrations toadjust the angle of operating member 54 with respect to the adjuster 53,and then a mounting means, such as a set screw, fixes the operatingmember 54 at the adjusted position. Incidentally, the operating member54 may be mounted to the adjuster 53 through a polygonal projection anda polygonal bore engageable therewith. The particular mounting means isnot critical.

In the fishing reel constructed as foregoing, the clutch lever 81 isoperated to disengage the clutch means 7 to allow the spool 3 to freelyrotate for casting, at which time the electric conductor 51 attached tothe spool 3 or spool shaft 4 rotates within the magnetic field of magnet50 and the direction of magnetic flux passing through the conductor 51changes in the rotation direction of conductor 51, following therotation thereof, whereby an eddy current is generated in the conductor51 by the change of magnetic flux, whereby a magnetic force in thereverse direction to rotation of conductor 51 is generated by aFleming's left-hand rule, thereby exterting the braking action on thespool 3.

The braking action is controllable by movement of magnet holder 52adjusted by the adjuster 53 and operating member 54. In other words, theadjuster 53, when rotatably operated, transmits its operating force fromthe cam groove 53b to the holder 52 through the engaging projection 52cand the holder 52 moves radially with respect to the support cylinder21a as the engaging position of the engaging projection 52c with the camgroove 53b changes, whereby the magnet 50 changes in position withrespect to the conductor 51 within in a range from the position wherethe clearance between the magnet 50 and the conductor 51 is the maximumto the position where the same is the minimum, thereby changing themagnetic flux density and adjusting the braking action exerted onto thespool 3. Accordingly, the braking effect can be adjusted to a minimum asdesired by angler prior to the casting.

On the other hand, in a case of using the operating member 54, theangler touches the finger of his hand gripping the rod to the free endof operating member 54, thereby rotating it in the direction of thearrow X in FIG. 2. The operating force, similarly to the directoperation of adjuster 53, is transmitted therefrom to the holder 52 sothat the holder 52 moves radially outwardly with respect to the supportcylinder 21a. Hence, the magnet 50 shifts from the maximum clearanceposition to the minimum with respect to the conductor 51, so that themagnetic flux density increases to increase the braking effect.Accordingly, during the casting, when the fishing rig arrives in thevicinity of the surface of the water and the backlash tends to occur,the angler operates the operating member 54 by the finger of his handgripping the rod carrying the reel body A to abruptly increase thebraking effect, thereby ensuring the elimination of backlash. Theoperating member 54 is manually restored, but it may be restoredautomatically by the use of a spring or the like.

Also, in FIGS. 1 and 2, a number of serrations 53d are providedcircumferentially at the outer periphery of adjuster 53, and a retainer57 formed of a flexible plate member is fixed at one end to the sideplate 22 by calking or the like, the retainer 57 engaging at the otherend with one of serrations 53d, thereby maintaining the adjuster 53 inits adjusting position. The retainer 57, during the rotation of adjuster53, is bent to disengage from the serration 53d.

In addition, in FIG. 1, reference numeral 58 designates a magnetic ringprovided at the inner periphery of bearing housing 21 opposite to theconductor 51, and 59 designates a C-like shaped snap ring for lockingthe holder 52 to the support cylinder 21a.

Alternatively, the magnet 50 may be shifted circumferentially or axiallyof spool 3 to adjust the position of magnet 50 with respect to theconductor 51, or the conductor 51 may be moved radially,circumferentially or axially of spool 3 to thereby adjust its positionwith respect to the magnet 50. In this case, the magnet 50 is mounted onthe spool 3 or spool shaft 4, the conductor 51 being supported, forexample, to the support cylinder 21a movably radially, circumferentiallyor axially with respect to the magnet 50. In brief, the magnet 50 andconductor 51 need only be adjustable in position relative to each other.Also, the magnet 50 may be provided radially outwardly of the conductor51.

The operating member 54 alternatively may be integral with the adjuster53. However, the operating member 54, when separate therefrom, isadvantageous in that the angler can dispose the operating member 54always in the most suitable position for adjusting the braking action.Also, the operating member 54 alternatively may project from within thesecond side frame 2 radially outwardly of spool 3, and may be mounted tothe adjuster 53 through an intermediate member, and may be provided atthe first side frame 1 carrying the handle 31 or between the first andsecond side frames 1 and 2. In brief, the operating member 54 need onlybe positioned operably by the finger of angler's hand gripping thefishing rod.

Furthermore, the operating member 54 alternatively may operate theadjuster 53 to decrease the braking effect from the preset minimumintensity adjusted by the adjuster 53.

Next, explanation will be given of a modified embodiment (a secondembodiment) of the invention in accordance with FIGS. 5 through 10.

This embodiment provides two first and second adjusters 531 and 532, thefirst adjuster 531 serving to adjust the braking action exerted on thespool 3 at the initial stage of casting, the second adjuster 532providing an operating member 540 operable by the finger of an angler'shand gripping the rod, so that the operating member 540 can control thebraking effect having been adjusted by the first adjuster 531.

In addition, in FIGS. 5 through 10, components which are the same asthose in the former embodiment (the first embodiment) are designated bythe same reference numerals.

In FIGS. 5 through 10, a brake 5 similarly to the first embodiment,comprises a cylindrical electric conductor 51 mounted to the spool 3concentrically with the spool shaft 4, a magnet holder 52 ofnon-magnetic material having a magnet holding portion 52a and anelliptic bore 52b at the center, and a magnet 50 held to the magnetholding portion and opposite to the inner periphery of conductor 51.

The second embodiment provides a control member 533 disposed in contactwith one side of holder 52 and having at the center an elliptic shaftbore 533a. The holder 52 and control member 533 are supported at theelliptic bores 52b and 533a thereof to the outer surface of supportcylinder 21a at the center of bearing housing 21 in relation of beingmovable radially of support cylinder 21a and provide pairs of springseats 52d and 533b opposite to each other at the predetermined intervalsin the moving directions of holder 52 and control member 533. Also,springs 534 are interposed between the spring seats 52d and 533brespectively and bias the holder 52 to have the maximum clearancebetween the magnet 50 and the conductor 51. The spring seats 533b engagewith engaging portions 52e provided at the outer surface of holder 52 tothereby control a moving range of holder 52 biased by the springs 534. Aguide bore 21c for radially guiding the holder 52, similarly to thefirst embodiment, is formed at the bottom wall 21b of bearing housing 21and shifts from the center thereof, into which bore 21c is inserted anengaging projection 533c provided at one side of control member 533. Afirst adjuster 531 having a knob 531a for rotary operation is supportedrotatably onto the support portion 21d at the outer surface of bottomwall 21b of bearing housing 21. Furthermore, the first adjuster 531,similarly to the first embodiment, is provided at the inner surface witha cam groove 531b of a circular arc and shifting circumferentially fromthe outer periphery toward the center, the cam groove 531b insertablyengaging with the engaging projection 533c perforating through the guidebore 21c. The knob 531a is exposed outwardly from the cover 23 so as tobe operable from the exterior so that the adjuster 531 rotates to changethe engaging position of engaging projection 533c with the cam groove531b, thereby moving the control member 533 and holder 52 radially withrespect to the support cylinder 21a, thus adjusting the magnet 50 inposition with respect to the conductor 51. A second adjuster 532 issupported rotatably to the second side frame 2 and has a contact portion532a which enters into the bearing housing 21 through a window 21eprovided at the peripheral portion of bearing housing 21 and which comesinto contact with a stopper 52f provided at the outer surface of holder52. The second adjuster 532 is rotatably adjusted to increase thebraking effect already adjusted by the first adjuster 531.

Also, the second adjuster 532 has a support shaft 532b journalled to thefirst and second side frames 1 and 2 which carries the operating member540.

Thus, the operating member 540 interposed between the first and secondside frames 1 and 2, is easily operable by the fingers of angler's handgripping the rod during casting.

When using a fishing reel of the above construction, the first adjuster531 is operated to adjust the braking action at the initial stage ofcasting by rotating the knob 531a at the first adjuster 531.

Now, the knob 531a is operated to rotate the first adjuster 531 tochange the engaging position of cam groove 531b with the engagingprojection 533c and an operating force of adjuster 531 is transmitted tothe holder 52 through the projection 533c, control member 533, springseats 533b and springs 534, so that the holder 52 together with thecontrol member 533 is moved radially with respect to the supportcylinder 21a. Hence, the magnet 50 held on the holder 52 changes inposition with respect to the conductor 51 in the range from the maximumclearance to the minimum clearance between the magnet 50 and theconductor 51, whereby the density of magnetic flux passing through thelatter is changed to enable adjustment of the braking effect on thespool 3. Accordingly, the angler can desirably adjust the braking effectto a minimum prior to the casting.

Then, during casting, the second adjuster 532 is operated to furtheradjust the braking effect. In this case, the angler pushes the operatingmember 540 by the finger of his hand gripping the rod to rotate it inthe direction of the arrow X in FIG. 6, so that the operating force istransmitted from the contact portion 532a at the second adjuster 532 tothe holder 52 through the stopper 52f thereof and the holder 52 is movedradially outwardly with respect to the support cylinder 21a and controlmember 533, whereby the magnet 50 at the holder 52 shifts with respectto the conductor 51 from the position where the clearance between themagnet 50 and the conductor 51 is adjusted to a maximum to the positionwhere the same is adjusted to a minimum, thus increasing the magneticflux density for the conductor 5 and also the braking effect.

Therefore, the second adjuster 532, when the fishing rig arrives in thevicinity of the surface of the water, is operated to abruptly increasethe braking effect on the spool 3 to ensure elimination of backlash. Inaddition, the second adjuster 532, after being released, returnstogether with the holder 52 by virtue of the springs 534.

In addition, the first adjuster 531, similarly to the first embodiment,is maintained in its adjusting position by use of a number of serrations531c and a retainer 57 engageable therewith.

In this embodiment, the magnet 50 alternatively may be movedcircumferentially or axially of spool 3 to be adjusted in position withrespect to the conductor 51, or the conductor 51 may be moved radially,circumferentially or axially of spool 3 for the same purpose. In thiscase, the magnet 50 is mounted to the spool 3 or spool shaft 4, theconductor 51 being mounted to, for example, the support cylinder 21a inrelation of being movable radially, circumferentially or axially withrespect to the magnet 50.

In brief, the magnet 50 and conductor 51 need only be adjustable inposition relative to each other.

The magnet 50 alternatively may be provided outside the conductor 51.Also, in a case of moving the magnet 50 radially of spool 3, other thanthat the separate control member 533, as shown, is moved together withthe holder 52 when adjusted by the first adjuster 531 but the holder 52only is moved when adjusted by the second adjuster 532, the controlmember may be integral with the holder 52. In this case, for example, arelief space for the engaging projection 533c is provided at the outsideof cam groove 531b at the first adjuster 531.

The operating member 540 may utilize a thumb rest, or be separatetherefrom. It is preferable to provide the operating member 540 betweenthe first and second side frames 1 and 2, but it may be provided ateither side frame. In brief, it need only be operable by the finger ofan angler's hand gripping the rod. Also, the second adjuster 532alternatively may be movable, for example, radially of spool 3.

Alternatively, the second adjuster 532 may be operated to decrease thebraking action having been adjusted to a maximum by the first adjuster531.

The abovementioned first and second embodiments adjust the brakingeffect by adjusting the movement of magnet 50 away from or toward theconductor 51. Alternatively, a plurality of pairs of magnets 501 and502, as shown in FIG. 11, may be disposed at both sides of conductor 51and held to first and second magnet holders 521 and 522, so that theoutside magnets 501 or inside ones 502 (the inside magnets 502 in FIG.11) may be changed in circumferential position with respect to the othermagnets (the outside magnets 501 in FIG. 11) by circumferentially movingthe holder 522 of the inside magnets 502, thereby adjusting the brakingeffect.

In FIG. 11, the support portion 21d at the bearing housing 21, as inFIG. 1, provides a rotatable adjuster 53, with which an engagingprojection 522c at the holder 522 engages, thereby moving the holder 522in association with the adjuster 53, the adjuster 53 providing theoperating member 54.

In addition, the holder 521 holding the outside magnets 501 is fixed tothe inner periphery of bearing housing 21 through a cylindrical magneticmaterial 551.

The inside magnets 502, as in FIG. 1, are fixed to a recessed holdingportion 522a through a magnetic plate 55. Other structures are the sameas in the FIG. 1 embodiment. In addition, in FIG. 11, the componentswhich are the same as those in FIG. 1 are designated by the samereference numerals.

Incidentally, the construction in FIG. 11 is applicable to theembodiment shown in FIGS. 5 through 10.
